Another common desalination process is Reverse Osmosis. It involves a solvent passing through a semi-permeable membrane; meaning this particular membrane only allows some molecules to penetrate or pass through. The solvent will then go into a solution with higher concentration of molecules.
Most genetically engineered fish are used in basic research in genetics and development. Two species of fish, zebrafish and medaka, are most commonly modified because they have optically clear chorions (shells), rapidly develop, and the 1-cell embryo is easy to see and microinject with transgenic DNA.ome GM fish that have been created have promoters driving an over-production of all fish growth hormone. This resulted in dramatic growth enhancement in several species, including salmonids, carps and tilapias.
The U.S. government may be about to approve genetically modified (GM) salmon from the company AquaBounty. If the salmon is allowed, it will become the first genetically modified animal heading for our dinner plates. The salmon is genetically engineered to grow faster, and the company therefore argues that the fish will help to feed a hungry world. Here once again we have the GM industry proclaiming it is going to save the World. This time with a luxury product, salmon, of all things.
